Interface Summary

Interface	Description
DirectConfirmationMeasure	This interface is implemented by all confirmation measures which are using the probabilities directly.
LogBasedCalculation	This interface defines the epsilon used by log based calculations for avoiding the logarithm of 0.

Class Summary

Class	Description
AbstractUndefinedResultHandlingConfirmationMeasure	An abstract class of all confirmation measures which have to handle undefined results.
CondProbConfirmationMeasure	This confirmation measure calculates the conditional probability of W' given W*. result = P(W',W*)/P(W*)
DifferenceBasedConfirmationMeasure	This confirmation measure calculates the difference between the conditional probability of W' given W* abd the marginal probability of W'. result = P(W'|W*)-P(W')
FitelsonConfirmationMeasure	This confirmation measure calculates the difference of the conditional probability of W' given W* and the conditional probability of W' given ¬W*.
JaccardConfirmationMeasure	This confirmation measure calculates the Jaccard similarity between W' and W*. result = P(W',W*)/P(W' v W*)
LikelihoodConfirmationMeasure	This confirmation measure calculates the Likelihood similarity between W' and W*. result = P(W'|W*)/(P(W'|¬W*) + e) The e is defined by LogBasedCalculation.EPSILON.
LogCondProbConfirmationMeasure	This confirmation measure calculates the logarithm of the conditional probability of W' given W*. result = log(P(W',W*)/P(W*))
LogJaccardConfirmationMeasure	This confirmation measure calculates the logarithm of the Jaccard similarity between W' and W*. result = log((P(W',W*) + e)/P(W' v W*)) The e is defined by LogBasedCalculation.EPSILON.
LogLikelihoodConfirmationMeasure	This confirmation measure calculates the Likelihood similarity between W' and W*. result = (P(W'|W*) + e)/(P(W'|¬W*) + e) The e is defined by LogBasedCalculation.EPSILON.
LogRatioConfirmationMeasure	This confirmation measure calculates the logarithm of the ratio between the joint probability of W' and W* and the product of the two marginal probabilities. result = log((P(W',W*) + e)/(P(W')*P(W*))) Another name for it is pointwise mutual information (PMI).
NormalizedLogRatioConfirmationMeasure	This confirmation measure calculates the logarithm of the ratio between the joint probability of W' and W* and the product of the two marginal probabilities.
OlssonsConfirmationMeasure	This confirmation measure calculates Olssons coherence.
RatioConfirmationMeasure	This confirmation measure calculates the ratio between the joint probability of W' and W* and the product of the two marginal probabilities. result = P(W',W*)/(P(W')*P(W*))
ShogenjisConfirmationMeasure	This confirmation measure calculates Shogenjis coherence.
